The Mayans used a dot (.) for 1, a line (_) for 5, and a shell for 0. There are 3 main layers. 400 place value, 20 place value, and 1 place value. The Mayans based on a 20 number system because of 10 fingers and 10 toes. The Mayan read and wrote their numbers up and down instead of left and right. This is a very hard question. I hope you understand!!!
Scribes are people who write things down. They could be keeping records of anything that it was important to write down.
The Greeks used a combination of addition and subtraction to perform subtraction in their numeral system. They would determine the difference between two numbers by adding the complement (the number that, when added, would equal the base of the numeral system) of the subtrahend (the number being subtracted) to the minuend (the number being subtracted from). This process involved breaking down the numbers into their place values and performing the necessary computations.

By keeping a notebook to write down ideas
There are an infinite number of rational numbers between 2.3 and 2.4 .Any number you can write down on paper that falls in that range is one of them.They include . . .2.30000000012.332.342.352.362.3600000000002372.392.3912.391012.39101012.3992.39992.3999999999
0.6991 and 0.6992
Calculate the difference between each number and the next number. Write them down. It should be quite obvious from there.
you can just do this. write the numbers down and go to the exact middle 24 25 26 27 28, the middle number between those two numbers (24 and 28) would be 26.
To get a complete list, just sit down with a pencil and some paper, write down '10,000', and then write down all the other counting numbers until you get to '99,999'. There are 90,000 of them.
100.00001
the page isn't big enough to write down the number
There's an infinite list of rational numbers that are all between 2.1 and 3.9 .Here are a few of them:2.112.122.22.32.42.62.72.92.992.999999999993.0..etc.Any number that you can completely write down on paper is rational.
Then either there is no mode or you write down that all the numbers are the mode.
Well, see, that's going to be a problem, since there are an infinite number of them, and we're a little busy just now. But you can easily generate the list for yourself. Here's how: -- Start at ' 1 ', and count. -- Throw out the first number, then write down the second number. -- Throw out a number, then write down the next number. -- Throw out a number, then write down the next number. -- Throw out a number, then write down the next number. -- Throw out a number, then write down the next number. Keep going like that. The list you write down will be a list of numbers that have ' 2 ' as a factor. You can just keep right on going for as long as you want, and make that list as long as you want it to be. You can also stop whenever you want to, and then you'll only have another infinite number left to go.
a median is the number in the middle of the set. if you come down to 2 numbers, find the number in between those two.
The only prime between 8 and 12 is 11.To find out if a number is prime, just try dividing it by all prime numbers between 2 and that number (including 2). The easiest method to do this is to write all numbers from 2 to your number down. Then cross out all numbers divisible by 2. Now cross out all numbers divisible by the next lowest number that is not crossed out (which is 3). Repeat this last step (the next number should be 5, then 7, then 11) until you reach your number, or you cross it out. If you have crossed it out, it is not a prime number, and if it has not been crossed out it is a prime number.
